SOIL-PULVERIZER.

SPECIFICATION forming part of Letters Patent No. 305,591, dated September 23, 1884.

u Application filed April 15, 1884. (No model.)`

To @ZZ whom it may concern:

Be it known that I, WILLIAM R. HrNDs, of /Vaterman, in the county of De Kalb and State of Illinois, have invented .a new and useful Improvement in Soil-Pulverizers, of which the followingis a description, reference being had to the accompanying drawings, in whichy Figure l is a plan View showing the knives to of the machine in a vertical position. Fig. 2

is a side view of the same. Fig. 3 is a vertical longitudinal sectional view of a portion of said machine, ltaken upon the line .r m, Fig. 1, viewed in the direction of the arrow there I 5 shown. Fig. 4 is a perspective view of one of the knives or cutters, showing` the means by which the same is secured to the frame. Fig. 5 is a front detail view of aportion of said machine, showing the mechanism for ad- 2o justing or oscillating the cutters. Fig. 6 is a transverse sectional view of the frame-work of the machine with thc cutters removed, showing a modification of the mechanism :for adj usting the knives as to depth of cut; and Fig.

7 is a rear view of said machine, showing the manner in which the front and rear cutters are adjusted as to each other when in use.

Like letters of reference indicate like parts in the different figures.

The object of my invention is to provide a `soil-pulverizer in which straight or substantially straight knives or harrow-teeth may be lused for cutting the soil, the respective positions of 'which may be varied laterally to any extent and whenever desired, while at the same time they may be adjusted at will as to depth of cut. A further object is to provide a seat upon said machine which may be so adj usted Vas to cause the weight of the driver to 40 bear upon any desired point, thus enabling said machine to be more perfectly balanced while in use, all ot' which will be hereinafter more fully described, and definitely pointed out in the claims.

In the drawings, A A represent the framework of the machine, which consists of two transverse horizontal bars, preferably made of angle-iron, as shown, and coupled to each other by loose or hinged couplings c c, which I prefer to construct in a V shape, or in any form whereby the rear cross-bar may follow the other without lateral movement. Said couplings a c connect with eyebolts c c a2 a2 ci a2, secured in the usual manner. to said bars A A. `A tongue, B, provided with a crossbar, b, suitably braced, is hinged or connected with the cross-bar A by means of the eyebolts b b' b2 b2, or in any well-known manner.

Bolted to the horizontal iiange of the crossbars A A, respectively, by means of bolts c, are a series of plates, C, each of which is provided with downwardly-projecting lugs c c', (better shown in Fig. 4,) forming pivotal bearings for a like number of clampplates or castings, l), which are provided with short arms or projections (l d, adapted to tit loosely in holes in said lugs c. Said castings are constructed with lateral and downwardly-projecting flanges d d2, to the latter of each of which are secured by bolts c c, knives or cutters E, so adjusted thereto as to project downwardly or at an angle oblique tothe plane of the horizon, substantially as shown in Fig. 2. Each of the plates D is provided with an arm, d", which projects upward from the bearingor axis `of said plate, and is provided with apin,

rl, extending outward therefrom. Said series of arms d upon the respective cross-bars A A are connected with cach other by means of bars F F, loosely pivoted to the pins di, asindicated in the drawings, or connected therewith by bolts or screws in such manner thata longitudinal movement of either of the bars F F will produce an oscillating or vibratory movement of the cutters E in a direction opposite to that of the movement of said bar. Thus it is obvious that by moving said bars the cutters connected with the same, respectively, may be moved laterally at any angle of Obliquity to the cross-bars A A. To control this movement and adjust or change the position of said cutters, as desired, at will, I have provided the following-,described device: Levers GG-tl1elo\ver ends of which respectively are pivoted to lugs or plates y g", Figa?, in the manner more clearly shown at g, Fig. 5, or to the cross-bars themselves-are pivotally connected with said bars F F, respectively,

as shown in said last-named figure. Concentric with Vsaid pivotal points in thelugs g g', I place notched arch-bars H H, which are rigidly secured by bolts or otherwise to the cross-bars AA', respectively. The levers G G are provided. with the usual detents, g'l y, re-

tained lin their normal positionsin the notches l uponsaid links, whercbythe former may be 6 5 of said arch-bars by springs in the usual manner, and operated by rods and hand-levers, as shown. Said levers GG fully control said lateral movement of thecutters,'ashereinafterv more fully described. A lever, I, Figs. l, 2, and 6, is bolted rigidly to the cross-bar A, as shown in Fig. 6, and extended upward therefrom, the vsame being detachably connected with the tongue B by a bar, J, Figs. l and 2, which is pivoted to saidv tongue at j. The upper'end of said bar is curved and provided with notches j', adapted to engage with a staple, ji, upon the side of the lever I, which serves as a guide for the bar J, and through which the lat- 'Ihe opposite end of the bar J has an upward projection or foot-rest, j, Fig. 2,

by means of a pressure upon which the notches the top of which is pivotally connected Iby means of a link, 7c, to the lever I at a distance upward from the cross-bar A corresponding to the length or upward extension of said bar or bracket K, or thereabout, thus causing the link k and the coupling-links a a to be horizontally parallel with each other, or substantially so.

When the tongue is maintained at the usual height atwhich it is held when in use, the cutters E should stand obliquelyto the ground, somewhat as shown in Fig. 2. By moving thel lever I backward or forward, this position may be varied and the angle of Obliquity of the cutters increased or diminished at will, and as the links 7c and a and the lever I and bracket K move in parallel lines with each other, it is obvious that any movement of the bar A through the lever 'I must produce a corresponding,movement in the bar A', and thus the changes in the movement of the cutters upon said respective bars are necessarily uniform. The movement of the le ver I'produces a rocking movement in the bars A A, a forward movement serving to reduce the depth of out, whi le a back ward movement tends to increase it.

vIt is obvious to one skilled in the use of this class of machines, that the same may be adjusted and used without as well as with a seat, though I prefer the. use of one, which may be constructed as follows: An inclined supporting-bar, L, provided with straps Z Z bolted thereto at its lower end, is pivoted, by means of a bolt, to the'tongue at Z', the seat L' being secured in 'the usual manner to the top of said bar. Braces Z2 Z2 are pivotally bolted to the bar L near said seat, as shown, kwhile the lower ends of said'bars are adjustably secured to the coupling -links a a by means of the bolts Z3 Z, the tightening or loos` ening of which serves to tighten or loosen the pressure of the loops in the ends of said bars moved to any position uponthe latter, thus enabling the weight of the driver to bear at any pointrequired. It is manifest that the seat, while thoroughly braced, will automatically adjust itself to the changes in the roeking movement of the bars A A produced by the action of the lever I. The levers I and G G' are within easy access from the seat L', and may be readily moved while the machine is in operation. Y

Byvre'ferencc to Fig. V7, it will be seen that by drawing the levers G G toward each other a lateral inclina-tion may be given to the re spective series of cutters in opposite directions, by which means the cutters upon the cross-bar A' may bc made to follow and cultivate the ground in the spaces left vby the cutters upon` the bar A. v f

It is apparent that the relative inclination ofthe two series ofcutters should be the same at all times, inorder to produce a rectilinear movement of the machine. Shouldy said cutters become clogged. a movement of the levers while, the machine is in use will serve to clean and free them from obstruction, when they may be vagain adjusted as before,without stopping'the machine.

As a modification ofthe meansfor produc ing the rocking movement described for varying the depth of saidcutters, the bar J, instead of being pivoted to the tongue atj, may be pivoted to a lug, as atj, Fig. 6, upon the bottom of the cross-bar A', and extended upward to connect with the loop ji, as shown, in an opposite direction from that above set forth.

Having thusdescribed my invention, what I claim, and desire to secure by Letters Patent, iS- y l. In a soil-pulverizer, the combination of the cross-bars A A', hinged couplings a a, pivoted cutters E, castings D, having arms (Z3, united by rigid bars F F', levers G G', for reciproeating said bars, bracket K, lever I, and bar J, all constructed and operating substantially as and for the purposes set forth.

2. The combination, in a'soil-pulverizer, of

- double cross-bars flexibly connected with each other by means of links hinged thereto at their respective points of j uncture,a suitable tongue, pivoted cutters upon saidr cross-bars adapted to move laterally, a lever secured rigidly to one of said cross-bars and having a link-con nection with a bracket extending upwardly from the other, and meansfor locking said lever in a fixed position, whereby a uniform rocking movementmay be given to said crossbars in their adjustment, and the position of said knives varied at will to cut deep or shallow, substantially as described. v
